Abstract: Variously configured sub-laminate modules are provided, which comprise at least a first ply and a second ply, the first ply comprising fibers extending in a first orientation, the second ply comprising fibers extending in a second orientation. The second orientation is offset relative to the first orientation, which offset defines an acute angle between the two orientations. The acute angle is less than 90 degrees and in at least one embodiment, the acute angle is approximately 25°. In certain embodiments, the acute angle further defines an unbalanced structure of the sub-laminate module. In certain embodiments, the first and second plies may be further secured relative to one another in a non-crimped configuration. Composite laminated structures formed from various embodiments of the sub-laminate modules are also provided, at least some of which may be homogenized. Various methods of manufacturing the sub-laminate modules and the composite laminated structures are also provided.

Abstract: Various embodiments provide a bi-angle pliable tape for use in forming a composite laminate structure. The bi-angle pliable tape comprises: a longitudinal axis extending in a unidirectional machine direction; a first ply comprising fibers extending in a first orientation, the first orientation being offset relative to the longitudinal axis at a first angle of less than 30°; and a second ply comprising fibers extending in a second orientation, the second orientation being opposite the first orientation relative to the unidirectional machine direction. The first ply and the second ply are further secured substantially adjacently relative to one another by one or more yarns so as to provide a non-crimped configuration such that the bi-angle tape defines a pliable structure. Corresponding composite laminate structures and methods for making the same are provided.
